Fig. 2

Graphical representation of pollen vitality (PV%) in cultivated (Lu) and wild Linum spp. (Lb and Lg). Identical superscript letters on average PV% values for each individual species indicates that these values are statistically insignificant while, differed superscript letters indicate that the values are statistically significant (p < 0.05). PV% indicates pollen vitality percent. The ‘n’ value above each bar in brackets indicates the total number of pollen grains studied in each species. The cap-tipped error bars on each bar indicate the standard error for PV% of each species, calculated by dividing the standard deviation by the square root of the sample size. Shorter error bars with smaller caps imply higher confidence in the data point.
